Hi, would really appreciate your help. For some reason, I can-NOT download anything related to .dmg just by clicking on a "download here" or "click to download". The ensuing screen just freezes, with the progress bar at the bottom of the screen only going halfway, where it remains hung up. The only alternative is to right click on the download notice, and cick on "save link as"...and then get the .dmg file off of the desktop. The Apple people told me I'd need to bring my iMAC desktop into their stores, an expensive taxi ride for me, for them to solve this annoying problem. Any suggestions? PS: this happens whether i use Safari =or Firefox.
